Hemolytic anemia or haemolytic anaemia is a form of anemia due to hemolysis, the abnormal breakdown of red blood cells (RBCs), either in the blood vessels ...
Microangiopathic hemolytic anemia may be suspected based on routine medical laboratory tests such as a CBC (complete blood cell count). Automated analysers (the machines that perform routine full blood counts in most hospitals) are designed to flag blood specimens that contain abnormal amounts of red blood cell fragments or schistocytes .
DPT vaccination: Diphtheria-pertussis-tetanus (DPT) vaccination has been implicated in the development of autoimmune hemolytic anemia caused by IgM autoantibody with a high thermal range. A total of 6 cases have been reported; 2 followed the initial vaccination and 4 followed the second or third vaccinations.
Hexokinase deficiency manifests is associated with chronic nonspherocytic hemolytic anemia. [3] Hemolytic anemia seems to be the only clinical sign of hexokinase deficiency. [4] In 1967 the first case of hexokinase deficiency was described by Valentine et al, [5] since then, less than 50 cases have been reported. [6]
Autoimmune hemolytic anemia (AIHA), in which autoantibodies react with self red blood cells and cause their destruction. [5] This disease is marked by increased extravascular hemolysis, with laboratory findings including increased lactate dehydrogenase and decreased or absent haptoglobin in both warm and cold AIHA, and positive Coombs test.

ABO hemolytic disease of the newborn [1] Anti-Kell hemolytic disease of the newborn [1] Rhesus c hemolytic disease of the newborn [1] Rhesus E hemolytic disease of the newborn [1] Other blood group incompatibility (RhC, Rhe, Kidd, Duffy, MN, P and others) [1] Alloimmune hemolytic blood transfusion reactions (i.e., from a non-compatible blood ...
Thrombotic thrombocytopenic purpura (TTP) initially presents with a range of symptoms that may include severe thrombocytopenia (platelet count usually < 30,000/mm³), microangiopathic hemolytic anemia (evidenced by schistocytes in the blood smear), and various clinical signs such as petechiae, purpura, neurologic symptoms, myocardial ischemia ...
A hemolytic state exists whenever the red cell survival time is shortened from the normal average of 120 days. Hemolytic anemia is the hemolytic state in which anemia is present, and bone marrow function is inferentially unable to compensate for the shortened lifespan of the red cell. Immune hemolytic states are those, both anemic and nonanemic ...
